Cannott upload json lottie to the Média library

Hi, I wanted to use lotties in my web site but when I try to upload json files in my medai I have a msg : “Désolé, vous n’avez pas l’autorisation de téléverser ce type de fichier.” I am not autorize to upload that kind of file. I wonder if this limitation is due to a WP security setting, if so how can I change this setting to be able to uploads those json files ? Regards,
